Application filed August 21, 1912. Serial No. 716,276.

To all evil-m 2'25 concern: I

Be it. known that I, CHARLES J. Honors, a citizen of the United States,residing at Jeannette, in the county of Westmoreland and State ofPennsylvania, have invented new and. useful Improvements in Envelops, ofwhich the following is a specification.

This invention relates to en'velops and has fo an object to providemeans for securely sealing the envelop so as to prevent the same frombeing opened without detect-ion.

Another object of the invention is to provide an improved form offastening for the envelop whereby the separate flaps of the latter canbe securely connected together withoLit use of an adhesive.

In the drawing forming a portion of this application, and in which likeletters of ref erence indicate similar parts in the several views:Figure L is a view of the blank of Which the' envelop is formed. Fig. 2is a plan view of the envelop showing the sealing flap closed. Fig. 3 isa section on line 3-3 of Fig. 2. Fig.4 is a perspective view of the cap.Fig. 5 is a perspective view of the socket member. Fig. '3 is a sectionon line 6-6 of, Fig. 2.

The envelop is preferably constructed of a' single blank of materialwhich is provided with a. front portion 1, side flaps 2, a relativelylong end flap 3 which is substantially co-extensive in length witht-heportion 1, and a relatively short sealing flapct. The

.fiaps 2 are preferably of rectangular configuration and passingtherethrough and through thefiap '3 is a fastening device such as aneyelet A, as shown in Figs. 2 and 6 of the drawings.

A stem 5 is extended through the flaps 2 and 3, the inner end of thestem being rivet'ed or upset as at 6 against a washer 7, which latterbears against one side of the innermost fia-p 2. The stem is providedwith an integral flange 8 which is disposed outermost and against theinnermost flap 2. In this manner the stem effectually serves as aretainer to positively hold the flaps '2 and 3 of the envelop securelyconnected together and without the use of an adhesive.

The outer end of the stem 5 is provided with a substantially conicalhead9. The sealing flap 4 isprovidedwith a resilient socket member 10 whosejaws 11, while being slightly springy are extremely fragile whereby theywill become broken when excesslve pull is applied to the sealing flap.The jaws 11 are curved as at 12 toward each other and theirextremitiesextend par-V velop while in transit.

The socket member 10 is provided with a continuous flange 13 which isspaced from an adjacent portion of the member so as to define therewithan annular groove 14. The

cap member 15 of the fastener is secured at 16 to the sealing flap 4. Asshown the cap is provided with bendable tongues 17 that are adapted toride against the curved surfaces 12 of the jaws 11 and to engage in theannular groove 14 of the socket member whereby the latter and the capare secured together to the sealing'flap. The cap member forms a.complete housing so as to cover the locking extremities ofthe jaws l1and to protect the locking head 9. The'fiaps 2 and 3 are connectedtogether by. an eyelet A or the equivalent thereof so as to insureagainst lateral separation of the flaps at any pointsbetween theopposite 'ends of the envelop.

I claim An envelop including folded flaps and a sealing flap, a lockingstem securing the folded flaps together and provided with aconical-head, a socket member located on the inner 'side of the sealingflap and insenting an annular concavity and springy fragile jaWs curvedinto the inner walls of said concavity, the said jaws being adapted toreceive the head of the locking stem therethrough whereby portions ofthe jaws are invited under their inherent elasticity'into engagementwitha portion of the head, a protecting cap located exteriorly of thesealing flap and adapted to house the lork-' =ing terminals of the jawsand the head of eluding a member having 3. rolled edge prev the lockingstem when the latter is operatively associated with the former, and

tongues carried by the cap and adapted to be v In testimony whereof'Iafli x my signatu re extended through the sealing flap and to be inpresence of two witnesses.
